Cosmology can be strange, Communist Albania was stranger. This book takes a strange path through both, but arrives at worthwhile insights. The book mixmasters time sequences like many modern books, I will try to unmix it here.

Philosophy of Science

• xix childlike curiosity endures, neoteny
• xx benefits/justification, Faraday's "you will tax it someday"

Cosmology

• xvii we are part of a multiverse, with cross-talk to other universise due to quantum entanglement, predicting observables

• 06 Penrose: universe likelihood less than 10^(-101e123)

• 07 Hawking and Penrose singularity theorem 8-14 argument from entropy, big bang VERY ordered?
